| Dedicated power I'm sure they make transformers that can withstand flooding, but will the power companies cough up the money for them? | |
| Dedicated power It would seem like the transformers used would have to be somewhat sealed being that they are filled with oil. | |
| Dedicated power Bob carver designed power supplies can be a bit different than most other stuff on the market, so Jea48 you might be onto something with that theory. | |
| Dedicated power I don't believe too many manufacturers make a 240 volt sub or amplifier in the us. | |
| Dedicated power All copper#2 wire. Thanks for the links jea48, the voltage drop could have been from the captive power cord. | |
| Dedicated power I haven't checked street input connections, I had to install a new service about 28 years ago, because the ice on the roof took the mast down. I don't seem to have any problem with my hot tub or air conditioner. The breaker is only 2 years old. | |
| Dedicated power The feeder line from the main service panel to the sub panel is 65' and it's 2awg. That same sunfire sub did the same thing in my friends system and the circuit was only 20' from the main panel. 2800 watts is quite a bit of power. | |
| Dedicated power The lights are wired on a separate circuit, it was a 2800 watt sunfire subwoofer, playing telarc time warp. I've seen lights blink in too many different systems to believe it could just be dirty connections. It has to be voltage drop on the line. | |
| Dedicated power It's not just clean connections, I've had lights blink on a 15 amp circuit with powerful bass, but when I plug an electric heater into that same circuit the lights are fine no change. | |
| Dedicated power I would go with dedicated 20 amp circuits first. | |
| Dedicated power Thanks for the info, it wasn't answerd last time, at least not about bonding the sub panel ground rod or not to the main panel grounding rods. | |
| Dedicated power My question was about a sub panel on an outbuilding, a grounding rod has to be used here by code as well as the 2 by the service entrance. I know you have to bond the two at the main service, but do you have to bond the one at the sub panel to the... | |
| Dedicated power The one answer I can't seem to find anywhere is on a sub panel in an out building that the neutral is isolated from the equipment ground with a grounding rod, are you supposed to bond that ground rod to the service entrance ground rod. | |
| Dedicated power residential electric service is 240VAC, which is achieved using two 120VAC lines that are 180 degrees out of phase with each other. They are 180 degrees difference when measured to neutral not each other. | |
| Dedicated power What's with this on the same phase advice, residential electric service only has one phase it's a split single phase. |
